IMPROVEMENT INV FIRE-EXTINGUlSHERS.

Specification forming part of Letters Patent No. 165,627, datedOctoberlll, 1875; application tiled March 18,12%. ,A

To all whom it may concern Be it known that I, PHILANDER M. DOUGH- TY,ot' Louisville, in the county of Jei'erson and State of Kentucky, haveinvented certain new and useful Improvements in Fre-Extinguishers; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, whichwill enable others skilled in the art to whichit pertains to make and use the same, reference being had to theaccompany ing drawings and to the letters Vot` reference marked thereon,which form a part of this specication..

The nature of my invention consists in the construction and arrangementof a chemical nre-extinguisher, as will he hereinafter more fully setforth.

In the annexed drawing, Figure l is a longitudinal section of myreeextingnisher, and Fig. 2 is an enlarged section ofthe lid of the tankwith the devices attached thereto.

` Arepresentsthe tank ofmy fire-extinguisher, constructed ol'anysuitablematerial and of any desired form and dimensions, whether portable or tobe mounted on wheels. The bottom B ot' the tank is made funnel-shaped,andtrom its center extends the outlet-pipe C through the side of thetank. In this pipe is arranged a A stopcock, a, and a exible hose, D,with nozzle, is connected thereto in the usual manner.

The upper end of the tank is entirely open, and

provided with a lid or cover, E, which may be hinged or otherwisejointed to the tank on one side, and, when closed, is fastened theretoby any suitable means. The upper edge of the tank and lower edge of thelid are constructed to receive and hold packing b, ofrubber or othermaterial, so that when the lid is closed a perfectly gas and water tightjoint will be formed. By means ofthe lid E the ent-ire upper end of thetank A maybe thrown open, so as to facilitate thelling and reillingofthe tank in whatever place the same may be. To the under side of the lidE are attached two bottles or receptacles, G G, ot' any suitablematerial, for containing the acid and soda. rlhe lower ends ot' thesebottles are open and provided with flaring mouths, whichvare closed byStoppers H H, made of rubber or other suitable material,'and eachprovided with a metallic disk,

d, on its upper or inner side. On the outer or lower side ot' eachstopper H is an eye, e, through whichpasses the end ot' a rod, la, theother end of said rod passing through the eye on the' A other stopper.vFrom the center of therrod h another rod,I, extends upward through acentral tube, m, attached in the lid E. To the rod l is fastened a tube,n, which is open at its upper end and surrounds the tube m, the upperend of the exterior tube n pressing against a packing-ring,p, when thestoppers are in place. On the upper end of the rod I is a knob, J,between which and the upper end of the tnbem is a spiral spring, s,surrounding the rod I, which spring holds the Stoppers tightly in theirrespective bottles. The bottles Gr G are lilled when the lid E is thrownopen, and the stoppers then putin their place. The tank A is lled withwater and the lid E closed, when the machine is ready for operation.

When it is desired to use the machine it is only necessary to press downupon the knob J, when the rod h will at once remove the stoppers fromthe bottles; and said stoppers being, by their eyes e, hung on said rod,they will turn and hang in the position indicated by dotted lines inFig. 2. The soda and acid are thus simultaneously precipitated into thewater, and generating carbonio-acid gas, so that by opening thestop-cock a the water and gas will be forcibly ejected from the tank.

It will be observed that the three elementswater, soda, and acid-arekept entirely separate until needed for use, which is ot greatimportance for many reasons. The water, being alone in the tank, willnot corrode the stop-cock a, no matter how long it stands therein,whichis always the case when the soda is held in a more or less perfectsolution in the water. Gold water will not properly dissolve the sodaJ5; hence the full ett'ect can never be obtained. By precipitating thesoda and acid at one time into the water, the acid will heat the waterand also create an agitation therein, thereby taci l-itatin g thedissolution ofthe soda, so that the full efiects of the soda and acidare obtained..

A latch, L, may be arranged on the lid to lock the rod I, to prevent theaccidental removal ot' the stoppers H. I

rlhe object of the funnel-shaped bottom is to concentrate-the pressure,so that the liquid cnn be thrownrto a greater distance by the use'of'said bot-'tom than by any other kind.

' obtained in other machines, owing to its coming Ainto contact with thebulk of' the soda, thereby producing-the greatest possible commotion,thus sending the acid, as also the soda,

Y Vinstantaneouslyin' every directionthrough allY parts of the machine,producing the best results possible to. obtain.

` Having thus fully described myinvention, what I claim as new, anddesire to secure by Letters Patent, is-

1. 'Iphe tank A, provided with funnel-shaped bottom B and outlet-pipe G,with stop-cock a, as and for the purposes herein set forth.-

2. The combination of the stoppers H, with eyes e, rods h I, tubes m n,packing p, knob J, and spring s, all constructed substantially as andfor the purposes herein set forth.

3. .The tank A, in combination with the hinged cover E, provided withbottles for the soda and acid, the said cover being arranged to open anduncover the entire top of the tank, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two Witnesses.
